I know it sounds like bullshiat but I heard the same sound in Gambrills Maryland last year. It was accompanied by a very intense low frequency vibration that literally made the air pressure feel like it was modulating very rapidly. The only way I can describe it was while I was hearing the sound, it was like I was inside a subwoofer speaker but the sound definitely was coming from the sky.

I stopped an looked all around there was nothing close within 100 yards but the post office. The sound pressure was very high and I've never heard anything like it in my life. I felt it in my body as much as I heard it.

My brother insists I was hoaxed but I'm an engineer and for the life of me I cannot figure out how that could have been possible based on the shear energy of the sound and how far way I was from anything that could have made it. It was clearly coming from directly overhead but I saw nothing.

The only thing I can figure is that it's caused by some weird atmospheric phenomenon or possibly some interaction of the atmosphere and a solar wind or flare. .

nah...just the right atmospheric condition where sound is reflected downward from a source far away.some nights i can hear the clacking of trains on railroad tracks that are at least 5 miles away and it sounds like i am right next to it.it is a weird feeling.

Funny that you heard that sound...

Which is a farking movie sound effect, and this video is a hoax. You idiot.

I think the explanation in the article was correct. It sounded like something grinding against metal. My guess is the atmospheric conditions were perfect to bounce the noise towards the mountains which intesified it.

When I was a kid in southern CA we had the same thing in the mornings, and it would vibrate and make that same eerie sound. As a kid...I honestly thought it was the radio waves going through the house, that's what I made sense of it. My mother could hear it most of the time as well, and she didn't know what it was. My dad left for work early and never (AFAIK) heard it. We'd hear it...I want to say twice a month, my recollection is a lot more often than that, but ...child memory, impossible to say.

I would love to know what it was though. And if it was of a frequency that perhaps older people can't hear or something.

The Mayor of Terrace claims its just a city worker grinding a grader-blade for roadwork. Apparently they were going to do it again just to prove it, but so far no media has covered that mundane explanation. I'm not entirely surprised- if it IS such a simple thing, well... That's not sensational, that's not ALIENS or any such thing, so, let's not comment on that and instead continue to propagate the viral mystery...
